# Interfacial Mechanical Behaviors in Carbon Nanotube Assemblies

## TL;DR

This paper reviews the interfacial mechanical behaviors in carbon nanotube assemblies, highlighting how interfaces influence the overall mechanical properties of CNT-based materials across different scales.

## Contribution

It provides a comprehensive assessment of interfacial mechanics in CNTs, including individual, bundled, and macroscopic assembly levels, emphasizing their impact on material properties.

## Key findings

- Interfacial shear properties vary across CNT scales.
- Interfaces significantly influence mechanical strength of CNT assemblies.
- Assembly structure affects multifunctional properties of CNT fibers.

## Abstract

Interface widely exists in carbon nanotube (CNT) assembly materials, taking place at different length scales. It determines severely the mechanical properties of these assembly materials. Here I assess the mechanical properties of individual CNTs and CNT bundles, the inter-layer or inter-shell mechanics in multi-walled CNTs, the shear properties between adjacent CNTs, and the assembly-dependent mechanical and multifunctional properties of macroscopic CNT fibers and films.
